The Old Pierce House, Dorchester, Mass. Built 1635 


This admirably-preserved specimen of the earliest New England type of building is still owned by direct descendants 
of its builder, and is reverently cared for. In 1893 the walls were opened for repairs, and they were found to be stuffed 
between the studding with eel-grass, which was in a perfect state of preservation after more than two and a half centuries!* 
The Babcock House, Milton, Mass., built 1723, and other old houses in Connecticut, Nova Scotia, etc., have since been 
found to be insulated in the same way, and the eel-grass undecayed, thus proving beyond question the permanence of this 
fibre with which Cabot’s Sheathing and Deafening Quilt is made. 


*We have in a bottle in our office a sample of this 288-year old eel-grass, with a statement from the owner, as shown on page 2.

Non-Decaying 


e 9% is a scientifically-constructed insulator for making houses warm in winter and cool 
ult in summer, for insulating cold stores, refrigerators, ice-houses, etc., for deadening 
sound in floors and partitions, and for numerous other purposes. It was invented 
about thirty years ago, and its introduction has revolutionized insulating and sound- 

deadening methods in this country and abroad. 

Quilt is a felted matting of cured eel-grass stitched with strong thread, securely fastened, between 
two layers of exceedingly strong, tough ““Kraft’’ paper. The eel-grass fibres are long and flat, and cross 
each other at every angle, as shown in the illustration on page 2. This forms a thick, resilient cushion 
of small and irregular cells of dead air, confined by the ribbons of eel-grass. The structure thus built up 
—first a layer of matter and then a layer of air—makes an ideal muffler of noise. “The sound-waves are 


broken up and absorbed or dissipated.

Compare this structure with the ordinary so-called deadening felts. The latter are thin and dense. 
They are of about one-eighth the thickness of Double-ply Quilt, and they have no air-spaces and almost 
no capacity of absorbing sound. 

This is the reason why no practicable method of sound-deadening has ever been devised that is as 
effective as Cabot’s Quilt, the eficiency of which has been proved by over thirty years’ use in thousands 
of buildings of all kinds, and especially of the more difficult kinds, such as musical studios, schools, 
apartment-houses, bowling alleys, etc.

This matting contains thousands of small air spaces in which 
the air lies still and dead because these spaces are irregular in 
shape and the air cannot circulate. This construction also 
breaks up and absorbs sound-waves. 


Why Eel-Grass ? 


Quilt is made of eel-grass because that fibre has marvellous qualities that make it immensely 


superior to any other known. * 


1. It has the long, flat blade that is necessary to make the air spaces which 
furnish its great insulating power. A round fibre will not do it. 


2. It will not decay! This remarkable fact is proved by many examples, and 
we have in our office a sample of eel-grass that is over 288 years old. 


(See illustrations. ) 


3. It is absolutely sanitary and will not harbor insects or vermin. 


4. It is very uninfammable! It will char and shrivel under flame, but fire 
will not spread in it. No other vegetable fibre has this property, and it 
makes Quilt an actual fire retardent.f (See page 24 for evidence of 
actual cases where Quilt has saved several buildings from destruction 


by fire. )

* Quilt is the pioneer article of its kind. It has been frankly imitated by three or four products using waste flax, or tow, and cattle hair in place of eel-grass. 
Note that neither of these have flat fibres and that they have none of the qualities of eel-grass cited above. They will decay, harbor insects and vermin, and 
tow is the most inflammable of all vegetable fibres. “Like fire in flax’? is an expression used in Ireland, which is a flax country, to illustrate great speed. Of 


cattle hair a high authority says... is usually contaminated with bacteriological poison from its origin, and may also contain arsenic salts . . . it is not 


permanent, becoming fragile and powdered when very dry, and rotten when wet.

Carefully and Thoroughly Manufactured 


The materials used in Quilt are all scientifically selected for 
their value in producing the results desired, and the process and care 
of manufacture receive equally close attention. 


Wonderttllyie The Quilt covering is made of wonderfully strong 
Strong Paper Kraft’? paper that is almost untearable in ordinary 

usage. Workmen find it ‘‘rough-house”’ proof, while 
the weak papers commonly used cause great loss of time and material 
by tearing. ‘““Kraft’’ paper is so thin that it makes only a light 
envelope for the eel-grass matting from which Quilt derives its great 
non-conducting power for heat and sound. ‘The picture herewith, 
showing a web of Quilt sustaining a weight of nearly nine hundred 
pounds, illustrates its great strength. 


Stitches Will By a patented process the stitching of Quilt is 
Not Rip fastened so that it cannot rip out. This is very 

important, for if stitching rips the filling settles and 
falls apart, ruining the efficiency. Quilt is the only insulator that 
has fastened stitching.

Quilt so flexible that it can be used on any surface. It will go around pipes or into 
corners or over any projections without breaking the continuity of the insulation and at a minimum 
labor cost. In this respect it is far superior to any other insulating or 
deadening material that is made.

The First Scientific Sound Deadener 


Quilt is the first thing that was ever scientifically made for deadening sound. None of the so-called 
deadeners that had previously been used were made for sound-deadening purposes, but were brought into 
this field in a haphazard, groping way because no really efficient thing existed. They were absolutely 
ineffective because they had no sound-absorbing power. 
Sound travels in waves, and Quilt breaks up and absorbs 
these sound-waves, which pass through any dense or vibrant 
substance, but are lost in the elastic, laminated cushion of 
Quilt. Felts are dense and the sound freely passes through 
them, and this is true not only of plain felts, but of those 
that are pressed into corrugations, or coated with pitch, 
devices which are frequently resorted to for the sake of 
appearances. Mineral wool and other packings are not 
permanent. ‘They settle down and finally are reduced to 
a powder. Moreover, they can be used only between the 
floor timbers or studding, and cannot be intervened be- 
tween the floor itself and the timber and thus cut off the

Schoolhouse Deadening 


““Next to light and ventilation, sound-deadening is perhaps the most important item of schoolhouse 
construction.’’ Absolute quiet is essential for proper conditions of study, and if pupils are disturbed by 
the reciting, singing and marching that is going on above, below and around them, they cannot con- 
centrate upon their lessons and they are under a constant nervous strain. 

In this field Quilt has scored one of its greatest triumphs, and there are hundreds of schoolhouses 
in all parts of the country that have been deadened with it. We have a special illustrated booklet upon 
school-deadening, which will be sent on request. 

Triple-ply or Double-ply Quilt are mostly used for school work. The fire-resisting qualities of 
Quilt are of peculiar importance in schoolhouse 
construction. Quilt is so fire-resistant that it has 
saved many buildings from burning. (See page 24. ) 
This is true of the standard grades of Quilt, but if 
building regulations absolutely require the use of 
asbestos, as is still sometimes the case, Asbestos 
Fireproof Quilt can be used.

Deadening in Musical Studios 


Musical studios put sound-deadeners to the supreme practical test. Every room in such buildings 
is used for practice or recital of vocal or instrumental music, and unless each room is completely isolated 
from its neighbor’s strains of harmony the result is utterly distracting 

Cabot’s Quilt has a most wonderful record of success in this field, dating from the time of the 
Nebraska University Conservatory of Music, in 1894, as 
per letter below from Mr. Willard Kimball, Director, 
down to the present day, as will be seen from the accom- 
panying illustrations and letters upon this page and the 
especially interesting cases of the St. Paul’s Girls’ School 
at Hammersmith, Eng., and the James Milliken University 
on page 9. Dozens of other similar cases can be cited 
where Quilt has been completely successful in solving this 
very difficult problem iz actual use, not merely theoretically. 
‘This feature was considered so important by those in charge 
of building the New England Conservatory of Music and 
Conservatory Chambers, that they consulted Prof. Charles 
L. Norton, of the Massachusetts Institute of Technology, 
upon the subject, and he made the most elaborate and ex- 
haustive series of tests that probably ever have been made 
to determine what method of deadening should be used. 
‘The results were entirely in favor of Quilt, which proved Institute of Musical Art, New York 
to be by far the most efficient as well as by far the Deadened with Asbestos Quilt 
cheapest of all the methods used, and Professor Norton’s mace ia CS Secs 
conclusions were summed up as follows: 

‘The efficiency of the Cabot Quilt as a material 
for rendering the partition “sound-proof’ is so clearly 
demonstrated in these tests that | recommend it for use 
in the partitions for which these tests were made.’ 
(See pages 7 and 8.) 

Quilt was used in both partitions and floors with 
absolute success, and the other pictures and verbal evi- 
dence shown upon this page prove conclusively that Quilt 
can be relied upon even in the most difficult cases. 

As a further result of the above tests the Canadian 
Conservatory of Music at Ottawa also used Quilt for 
deadening, and the following letter shows their result:

Report of Charles L. Norton 
Sound-proof Partitions 
A Practical Scientific Test 


The subject of partitions for fireproof buildings is one which has led to much investigation, especially. by the New 
York City Building Department. 

When it is desired to make a partition which shall be reasonably sound-proof, it is apparently necessary, to diminish 
somewhat the absolute incombusti- 
bility of the partition, though to a 
less extent than was supposed. 

The following account of 
tests made for Mr. Edward T. 
Barker, architect of the dormitories 
of the New England Conservatory 
of Music, will show the relative 
values of some of the typical parti- 
tions as sound-proof separations be- 
tween rooms: 


There were built upon the 
concrete floor of the B. & A. 
warehouse, East Boston, five rooms 
7 feet square, whose side walls were 
made of the several partitions. The 
rooms were built upon a floor of 
the same kind as that which is to 


be used in the buildings for the Conservatory Chambers, Dormitories for the New England Conservatory of Music, for 
students of the conservatory, for ; which Prof. Norton’s Tests were made 
which the results of these tests were E. T, Barker, Architect, Boston 


especially desired. 

The rooms were built near one another on the fifth floor of the warehouse, in a large loft or room about 50 x 70 feet 
long and 9 feet high. The ceiling of each room was the under surface of the concrete ceiling of the large room. Each 
room had a floor of two thicknesses of 7-inch floor boards, with ¢wo thicknesses of Cabot’s Sheathing Quilt between the 
floor boards and the concrete slab of the main floor. On one side of each room was a door with a glass panel, the door- 
jambs being faced with soft felt, and the bottom of the door was fitted with a stop or ‘‘weather strip’? operated when the 
door closed, making a tight joint at the bottom. 

The side with the door will be referred to as the front in the following description. 

Room A — This room was submitted by the National Fireproofing Company, and its four sides were made of terra- 
cotta blocks. ‘The front and back walls were made of blocks 4 inches thick; the sides of 2-inch and 3-inch blocks. After 
the blocks were in position the room was given two coats of plaster inside and out. 

Room B was submitted by the Keystone Block Company, and its four walls were made of the blocks of the Key- 
stone material, of the nature of plaster of paris, with a fibrous bond. The front wall was of blocks 4 inches thick, and the 
left side was of blocks 2 inches thick, the back of blocks 3 inches thick, and the right side of two 2-inch blocks, with a 
2-inch air-space between them. ‘The entire room was given two coats of plaster inside and out, except the front, which 
had no plaster on the outside of the blocks. ; 

Room C was submitted by the Sackett Wall Board Company, and was built of Sackett plaster board 14 inch thick, 
wired upon both sides of 3-inch steel channels. The channel truss or studs of the back and right side were wrapped with 
felt about 1¢ inch in thickness before applying the plaster board. The Sackett plaster board is a composite board of alternate 
layers of paper and plaster, the whole being about 44 inch thick. This room, like the other, was plastered inside and out, 
but to a slightly less thickness. : 

Room D was submitted by J. Russell & Co., and was of a more complex construction. The left side was a solid 
partition of metallic lath and plaster. The 7%-inch steel ties were spaced 16 inches on centres, metal lath was applied to 
one side only of the ties, and then plastered to a thickness of 2 inches. The rear wall was built upon two rows of %-inch 
studs staggered. Between them was placed one thickness of waterproof paper about 3/5 inch thick, and metal lath was 
wired to both sides of the row of studs and given two coats of plaster. The right side was of the same construction, with a 
layer of 14-inch felt between the two thicknesses of waterproof paper. The front wall was of metal lath on two rows of 
staggered studs, with Cabot’s Seaweed Quilt between the rows of studs. 

Room E was submitted by Mr. Samuel Cabot, and was wholly of metal lath and plaster double partitions, with the 
space between the lath filled with Cabot’s Sheathing Quilt. The front and left sides contained three thicknesses of Quilt, 
and the right side and rear two thicknesses. ‘The Quilt was placed between the studs and the metal lath, and where three 
thicknesses were used, one was between the row of studs as well. 

The rooms had been vigorously dried for several days, none longer than a week, but the whole building was so 
damp and the time so short that no considerable part of the plaster and none of the interior portions of the partition were 
dry. The Sackett board room was the driest, and Caéot’s was the least dry.* 

The preliminary trials showed so great a range of efficiency of the several constructions that the microphonic apparatus, 
which was designed to make rapid comparisons of sound-intensity possible, could not be used. Reliance had to be placed 
wholly on listening with and without a felt-mouthed stethoscope at the outside of the partition to sounds of various quality 
and intensity from within. The notes of the piano, violin, cornet, and the human voice were carefully tried throughout 
wide ranges of pitch and intensity. The performers and the instruments were interchanged; every possible chance of 
unfairness, due to the variations of intensity in the sounds used, was eliminated. Of course no interchange of the positions 
of the room was possible. No electrically-driven tuning-fork could be used for producing sounds of constant loudness. 
The insulating property of some of the partitions was so good that not even the blare of a cornet or the overpowering tones 
of an Italian tenor, drawn from the ranks of the laborers on the building, could be heard through the partition except by 
careful listening within a few inches of the wall. 


*Note that the Cabot room (which was the last built) was the least dry, and bear in mind that water is a very perfect sound-conductor; yet in spite of this 
handicap Cabot’s Quilt was found to be much the best.— S. C., Inc. 


[e7o) 


After much consideration the writer has given the following 
ratings to the different partitions. The order of their standing upon 
the list indicates their efficiency as compared with those above and 
below them.

Nothing more is to be inferred from the numerical efficiencies than that the first partition is about three times as 
good as the last, and that the numerical interval between any two partitions on the list merely indicates the order of magnitude 
of the difference between the partitions. 

The partitions making up the rooms submitted by Samuel Cabot and the Sackett Wall Board Company were the most 
efficient; but it is distinctly to be borne in mind that no other room had so easy a test as did these, in that each of the others 
had one thin and ineffective side which transmitted sound to the sides adjacent to it. The thin side of the Keystone room 
was noticeably resonant, and plainly rendered it impossible to make a fully satisfactory test of the air-space partition. The 
solid metal lath plaster partition of the room submitted by J. Russell & Co. acted in the same way in that room. I do not 
believe, however, that this defect in the structures has caused any changes in the position on the efficient list of the Cabot 
and Sackett rooms. 

The efficiency of the Cabot Quilt as a material for rendering the partition ‘‘sound-proof”’ is so clearly demonstrated in 
these tests that I recommend it for use in the partitions for which these tests were made. The nature of the material in which 
the Quilt is encased should be carefully considered. I do not think it within the province of this report to discuss the par- 
tition from other than acoustic considerations, and as an encasing medium the most effective material is Sackett Board and 
Adamant Plaster. 

I would therefore give as my opinion that the best acoustic results would be attained by using a partition of Sackett 
Board and Plaster with two thicknesses of Cabot’s Quilt between the plaster board. I should recommend a wooden stud 
rather than steel channels if the fire risk is not materially increased thereby. 

As later tests showed, some sort of a suspended ceiling will be needed, as the concrete slab transmits the sound 
across the top of the partition readily. No trouble will be given by the sound passing through the concrete to the rooms 
above or below; but unless a layer of Cabot’s Quilt, with under-lath and plaster, or of Sackett Board and Plaster, be put 
on the under side of the concrete ceiling, the efficiency of the partitions will be diminished somewhat. 

The front walls could not be tested because of the leaks around the door and through the door frames, even where 
covered with a large shutter padded with Cabot’s Quilt. It is evident that a double glass door will be needed. The floor 
construction is acoustically good. Respectfully submitted, Cy NORGONE 

Boston, August 8, 1902. 


The Methods of Construction 
(See page 21 for photographs of types of construction used) 


Cabot’s Deafening Quilt was adopted for deadening in both the Conservatory of Music and the 
Students’ Dormitories, in accordance with the foregoing recommendation of Professor Norton, supple- 
mented as it was by the endorsement of all the other witnesses of the tests (including Mr. Edmund M. 
Wheelwright, of Wheelwright & Haven, architects of the Conservatory, Mr. Charles P. Gardner, 
President of the Conservatory, and Mr. Frank W. Hale, General Manager, who was deeply interested 
and whose letter we print below, Mr. E. T. Barker, architect of the dormitories, and many of the 
Trustees and Directors of the Conservatory), who were unanimously of the opinion that the superiority 
of the Quilt-lined partitions was even greater than Professor Norton’s conservative report indicates.

Dear Sir: 1 have become very much interested in the matter of sound-proof material for buildings containing 
musical instruments, and among other materials used for this purpose I had occasion to be present at a test wherein the 
Cabot Quilt was used. The test consisted of a room large enough to contain a pianoforte and several performers, the room 
being entirely covered with your Quilt. ‘The result was very satisfactory, so much so that I advised this material’s being 
used in the construction of the new building of the New England Conservatory of Music, and also in the new residences 


for women students. We have no doubt but that the result will fully meet our expectations.

“Tt may perhaps be of interest to give some further

the building should be sound-proof in this respect, and the 
work has been so carried out that it 1s impossible to hear any 
sound either through the floors or the partitions. Before this 
result could be arrived at many experiments had to be made, 
and it was finally resolved to construct the rooms according 
to the detail drawings published herewith.* From these 
drawings it will be seen that each room is practically an insu- 
lated box. ‘This has been achieved principally dy a careful 
use of Cabot’s Three-ply Quilt— a material which is made in

A Conclusive Sound Deadening Test 


The architects specified Cabot’s Quilt for 
deadening these Music Rooms and Studios, hav- 
ing successfully used it many times before for similar 
purposes, and knowing of its use in the New Eng- 
land Conservatory of Music, New York Institute 
of Musical Art, Canadian Conservatory of Music, 
and hundreds of other buildings, where complete 
deadening is essential. Makers of another product 
made strong and definite claims to the Trustees of 
superiority for their product over Cabot’s Quilt, 
and the Trustees ordered an elaborate test made. 
Two rooms were built, one deadened with Quilt 
and the other, of exactly the same construction, 
with the imitation, and the results were reported 
by the architects as follows:

From Letterof Mr. Edward Strong, Director: 


Northfield, Minn., June 12, 1915. 


“*T have your letter of the 9th inst., and in 
reply will say that Cabot’s Quilt was used in the 
construction of our new Music Hall and has proven 
entirely satisfactory. “The sound-proofing features 
of our building are a little unusual, and your Quilt 
was extensively used both in partitions and floors. 
Our rooms are divided by 9-inch walls, and in each 
one is an air space of about 4 inches. These inside 
wall surfaces are covered by the Quilt. Our build- 
ing is thoroughly fireproof and concrete construction 
throughout. The hardwood floors rest directly on 
two thicknesses of Cabot’s Quilt, which is laid on 
the concrete. The floors have proven absolutely 

“satisfactory in thesmatter of*sound-proofing and are 
clean and elastic. The Quilt is odorless and fire- 
proof, and does not seem to make any dust. JI am 
glad to testify to the excellent results we have 


obtained.”’ EDWARD STRONG.

““T have used your two-ply Deafening Quilt for the deafening of a building containing eleven music rooms on the 
main floor, while there are about eight classrooms on the second floor, immediately above. 

““Your material was put on the ceilings, on the floors, and on both sides of the partitions separating the music 
rooms from each other and from a corridor running lengthwise of the building, where it was tacked on to the studdings, 
joists, and floor lining and secured in place by 1 x 2-inch strips nailed directly over it. 

‘*T am pleased to say that I found this material to do just what you claim for it. The tests which were made with 
eleven pianos going on the first floor were very satisfactory. Nothing but a very faint sound of music could be heard in the 
rooms above as well as between the rooms.”’ FRITZ FOLTZ, Architect.

“Your Quilting was placed directly under the slab floor of the jail between the suspended metal lath ceiling of the 
court room, which is directly under the jail floor, and the insulation is perfect. When I suggested the placing of the jail 
on the two upper floors of the Court House the principal objection raised was that the yelling and noise of the prisoners 
would disturb those in the court rooms below.’’ HARVEY L. PAGE, Architect.

Sound-proof Apartments 


Civilized construction now requires sound-proof floors and partitions in apartment houses. Tenants 
have rebelled against apartments where they hear every noise made by their neighbors, and where alltheir own 
conversations may be heard by others. “The following —— 
pages show how the best modern buildings are now 
meeting this demand. No tenant will hereafter remain 
in a noisy apartment when he knows that he can rent 
one that has deadened floors and partitions. A sound- 
proof building insures more permanent tenants and the 
deadening isa first-class investment for this reason alone, 
but sound-proofing is an actual economy in construction 
on the modern plan. -It-saves:waluable_floor space and 
also reduces costs by lightening construction. 

Saves Valuable Floor Space—3-inch Parti- 
tions: Absolutely sound-proof partitions, even less 
than 3 inches thick, can be built with Cabot’s Quilt. 
Without this thin partitions would be too noisy to be 
tolerated. Even a 6-inch partition undeadened would 
not be sound-proof. This shows a great saving in 
floor space, and the income gained from this extra 
space will pay for the deadening many times over. 

Saves Weight in Construction: These thin 
partitions are very much lighter than the thicker and 
more noisy partitions ‘The total weight saved in the 
whole building is a very large item. 

Reduces Cost of Construction: The thin 
partition, deadening included, is cheaper than the 
heavy non-deadened construction ordinarily used. 

Sound-proof Floors deaden the noise of foot- 
steps, moving furniture, falling packages, romping 
children, dancing, etc. 

Sound-proof Partitions make conversations 


private and kill the nuisance of phonographs, radio- a 2 Mee Borin OAS AUNGY.

Dear Sir: We are pleased to acknowledge that the results obtained in the Apartment Building at the above address 
from the use of your Insulating Quilt for sound deadening have been highly satisfactory. 
Your 2-ply Quilt was hung in the centre of double partitions between adjoining apartments, which construction has 
minimized the transmission of sounds from one apartment to another im a very satisfactory manner. 
Our experience with your material in this building impels us to say that we would unhesitatingly use it in our future 
work of this character. Very truly yours, HARBY, ABRONS & MELIUS, Inc.

Sound Deadening in Hospitals 


Sound-proof floors and partitions are 
of great importance in hospitals. Patients 
who require quiet should be isolated from 
the noises above, below and around them. 

The sanitary qualities of Quilt — it 
will not get foul or rot, nor harbor insects 
or vermin — are of great value in hospital 
construction, and its fire-resisting properties 
are especially important in such buildings. 

Dozens of hospitals have been dead- 
ened with Quilt, such as the Butler Hospital, 
Providence, R. I.; the Women’s Hospital, 
Boston; Santa Rosa Infirmary, San Antonio, 
Tex.; St. Luke’s Hospital, New Bedford; 
Sydney Hospital, Sydney, N. S.; Boston 
Psychopathic, etc.

for lecture halls, for their sake; for dance

delightful touch of resiliency to a dancing floor. 


Gymnasiums, Club houses or other buildings con- 
Rinks, etc. taining gymnasiums, skating-rinks, etc., 
should be protected from the noises inevitable in such 
places. Quilt has been especially successful for all such 
purposes, as the following letters show: 


‘*Tn sound-proofing the floor of a Y. M. C. A. Hall, which 
formed at the same time the ceiling of the gymnasium below, we 
used five layers of Quilt, one inch of mortar, and a single thickness 
of ordinary felt, the latter being placed between the lining floor 
and the top floor. Upon completion of the work a test was made 
by gathering in the gymnasium a small crowd of boys under 
instructions to make all the noise possible by running, jumping, 
use of clubs, striking dumb-bells, etc. Except that some of this 
sound traveled through an air duct (which has since been changed), 
it was inaudible in the hall above, even with the ear placed upon 
the floor.”’

ago, would say that this material has given and is giving entire satisfaction, as we are 
troubled practically not at all by the noise from the gymnasium below.”’ 


H. T. WALLER, General Secretary Y. M. C. A., Cambridge, Mass. 


Secret societies which wish to remain secret must 
enclose their lodges with a sound-proofing. ‘The architects 
of the Boston Masonic Temple tried Quilt in the temporary lodges with such 
satisfaction that it was used in the splendid new building with the best results.

A Remarkable Case of Bowling Alley Sound Deadening 


One of the greatest problems of building bowling alleys in cities is the noise. The rolling balls and 
their impact upon the pins, as well as the falling of the pins themselves, form a combination of penetrating 
noises which has often made a bowling alley a very bad neighbor and has seriously lessened the value of 
adjoining floors or buildings. The problem of avoiding this was presented to architect Leon E. Stanhope, 
of Chicago, recently in a very acute form, because he had an old city building to remodel, with stores in 
the lower story, a high-class restaurant in the second story, and bowling alleys in the two floors above. 
There were eight alleys on each floor, and if the sounds from these alleys could not be kept out of the 


restaurant one or the other of these establishments would have

to go out of business, since a nice restaurant with a cabaret 
attachment cannot be expected to do business to the accompani- 2 CINDER S oh 
ment of the noises of a bowling alley. Mr. Stanhope solved the Levent Ne 
problem. He deadenedthe floorand ceiling above the restaurant 
with Cabot’s Triple-ply Quilt, laid as shown in this drawing, 
and the results were perfect, as described in his own words: 
Chicago, April 10, 1915. 
““ There are eight bowling alleys on third floor and eight on the 


fourth floor, placed directly over a very handsome Oriental Café which seats 
six hundred persons. Wath the entire sixteen alleys in operation the notse 1s

Cabot’s Quilt for Acoustical Correction 


Office in Boston Showing Method used with Remarkable Success in Correcting Acoustical Defects 
Room Full of Stencil-cutting Machines 


The report on this job says: 


“* Their carpenters laid one layer of Double-ply Quilt on ceilings and covered it with duck, one layer on walls and 
covered it with burlap, two layers on floors and covered it with lmoleum. All those interested in this department were 
astonished at the remarkable change brought about and very much pleased. Mr. Fiske says it has increased the production 
about 100% and that he hears no complaints from the girls about noise, whereas before a girl would only work a short time 


c) 


in such a noisy room and then leave.’ 


A good deal of mystery and a large bill of expense has been attached to the correction of acoustical 
defects in auditoriums and offices which are mainly caused by the echo or reverberation of sounds from 
hard wall plaster walls and ceilings. _Cabot’s Quilt will correct such troubles at very small cost. [It can 
be applied by any carpenter almost as easily as wall-board, and covered with upholstery burlap or with 
cotton cloth tinted to any desired color; and the expense is only about one-quarter that of the more 
elaborate methods. The fire-resisting qualities of Quilt, as well as its sanitary character, are especially 
valuable in such work. 

One of the first jobs of this kind ever done was in the New England Conservatory of Music, 
Boston, where a music recitation hall was so resonant that it could not be used. Panels of Quilt 
covered with burlap made the walls so dead that some of the panels had to be removed, and the conditions 
then became perfectly satisfactory. 


The story of the Franklin County Court, St. Albans, Vt., is told in the following letter from the 

contractors : 
St. Albans, Vt., April 14, 1916. 

“We are glad to inform you that we were entirely successful in deadening the echo in the Franklin County Court 
Room of this place, or so far removing it that conversation is easily heard in the room. 

*“ This room is about 50 feet square by 25 feet high, and the ceiling was beamed, forming panels about 12 inches deep. 

““ The beams were removed and the ceiling covered with a layer of your Asbestos Quilt fastened in place by being 
thoroughly nailed along the edges. 

“* Over this was placed a layer of natural colored burlap, also stretched and nailed and neatly panelled by means of 
V% x 3 wood strips painted in a darker shade and forming an attractive looking ceiling of cushioned panels. 

*“The echo in this room had been a great annoyance, it being almost impossible to hear the evidence of a low 
spoken witness. ”’ Yours very truly,

Cabot’s Quilt as a Fire-Protection 


Four Actual Cases’ where Buildings were Saved from Serious Damage or Destruction by 


Fire. Each Case Described by the Architect of the Building 


(The remarkable testimonials quoted on this page furnish the most conclusive and striking proof 
of the fire-resisting power of Quilt. They refer only to the Standard Quilt, paper covered, and not to 
the Asbestos Quilt. “The latter is even more fireproof and used in all kinds of fireproof construction. ) 


This schoolhouse was saved from destruction by 
fire by the Cabot’s Quilt that was used for deadening the 
floors, as described in the following letter:

floors a coat of some kind of liquid to lay the dust. This 
liquid was put on with a common cotton mop. In the 
evening, not having completed the work, the men left the 
pail and mop in the centre of the schoolroom, and during 
the night spontaneous combustion took place and burned 
up the pail and mop, together with some five or six square 
feet of the top floor, burnt down to the Quilt and went 
out. . . . This little instance has made many friends for 


ult.”

“You will be interested to know of an experience I had recently with your seaweed quilting, which proved it to be 
a good fire-resister. In finishing a room in my stable I covered the studding with one thickness of the quilting for warmth 
and then sheathed over it with pine sheathing, which was finally varnished. The room took fire from an over-heated stove 
and, although some of the sheathing burned completely through, the studding behind the sheathing remained in perfect 
condition and showed no trace of fire.”’

**T consider Cabot’s Eel-grass Insulating Quilt a wonderful fire-retardant. “Two years ago when rebuilding the 
North Side High School, which had been partially destroyed by fire, we found the Cabot’s Quilt which was used for 
sound-deadening undermeath the floor to be practically intact. The hardwood floor and furring strips over the material had 
been completely consumed in many instances. I think this fire test substantially confirms the claims of the Cabot Company 
as to the fire-resisting quality of their Quilt. J. E. PILGRAM. 


Minneapolis, May 27, 1915. 


“Tn the recent fire at the Mountain View Methodist Church ample testimony was given of the very high 
fire-resisting qualities of this Quilt. . . . the fire commenced in the 
outside wall, running to the roof, then burning downwards. When 
the fire reached the ground floor and came in contact with Quilt, 
this being used for deafening, the flames were checked and only 
made their way to the basement through an aperture made by 
falling of heavy timbers from above. After the fire among the 
ruins could be found large quantities of the Eel-grass Quilt, with 
only the paper covering destroyed by fire.’’

‘The Quilt was applied in longitudinal courses lapping at the adjacent edges 2% to 5 inches, averaging about 3 
inches. The 2 x 2-inch furring strips were attached over the Quilt around the edges of the panel and along the top of each 
joist, and was securely attached through the Quilt and rough flooring joist by 34-inch nails driven into each joist. The 
1 x 4-inch dressed and matched flooring was laid over the furring strips; 2!g-inch casing nails were used, one nail to each 
furring strip.”’

Quilt for Heat Insulation 


For Houses, to Make Them Warm in Winter and Cool in Summer; for Cold Storage, 
Fruit Storage and Ice-houses; for Refrigerators, Dryers, etc., and for 
Roof Insulation in Factories 


The laminated structure of the Quilt which makes it so efficient for breaking up and absorbing the 
sound-waves, also forms innumerable small air-spaces. These air-spaces are of irregular size and shape 
so that the air cannot circulate in them or through the Quilt, but lies as “‘ dead’’ as is possible. Dead 
air is the best of all heat insulators 

This structure makes Quilt perhaps the most efficient heat-insulator on the market. It is certainly 
equai in efficiency to any insulator at any price, and has many other advantages that no other insulator 
possesses. It is the only insulator that is now considered practicable which is fire-resistant, and the only 
one that is decay-proof and permanent. 


Hoe Quilt will pay for itself in two hard winters in saving fuel, to say nothing of doctor’s

‘Warm and Comfortable” — a remarkable story from frozen Alaska 
“*T used Cabot’s Quilt in constructing a cabin at Resurrection Bay, Alaska. The walls, roof and floor were rough, 
12-inch boards, double, with Quilt between the boards. Coming into the cabin at the end of a day’s work, I found it still 
warm and comfortable from the small fire used in getting breakfast twelve hours before, during all of which time the wind 
was blowing furiously from the north, the temperature being from 10 to 15° below zero.”’

All kinds of cold storage and ice-houses, as well as fruit storage, ice manufactories, 
and household ice-boxes, can be insulated with Quilt in the most effective and permanent 
way and at the lowest cost. The fire-resisting properties and sanitary qualities — decay 
and insect-proof —are of special importance in this construction.

Insulation 


Chicago, November 7, 1921. 


“You have asked us for our 
opinion as to the merits of Cabot’s 
Quilt for insulation. We are glad to 
say that we used it for such purpose in 
one of our buildings erected two years 
ago, using the specifications furnished 
by you as to the number and kind of 
layers required. 

“The first floor with this insula- 
tion is immediately above our engine 
room where the temperature at the 
ceiling often runs as high as 115° F. in 
the summer time, due to the fact that 
our boiler room immediately adjoins it. 
Between this ceiling and the floor above 
we have I-beams and brick arches and 
ten layers of your Quilt. Upon testing 
same we are able to bring the tempera- 
ture on this floor to 18° below zero and 
have had no trouble ever since, main- 
taining from 8 to 10 below zero, even 
when receiving and shipping goods. 
We have had no trouble with leakages 
of temperature or moisture. We donot 
hesitate to recommend your article.’

Insulated with Cabot’s Quilt 


Why go to the expense of building a concrete or brick fireproof building and then 
line it with four to eight inches of Cork, or some other inflammable wood or fibre 
insulator? The only fireproof cold storage building is the one built of 


CONCRETE OR BRICK, STEEL AND QUILT. 


Root Roofs of factories, office , 


insulation buildings, apartments, hotels, 

and all buildings where heat 
conservation is important, — and that means 
nearly all buildings,—should be insulated. 
This prevents escape of heat in winter, and 
in factories prevents the condensation of 
moisture upon the upper ceiling and conse- 
quent dampness and damage It makes 
the upper rooms cooler in summer by 1n- 
sulating against the heat of the sun.

Grades of Quilt 


1. Single-ply is the grade commonly used for lining houses and similar work. One layer is equal to 
twenty-eight of common paper. It is about %-inch thick. 


2. Double-ply is used for sound deadening, cold storage insulation, and for all house and similar 
work where special results are required. One layer is equal to more than forty of common 
paper. It is about %-inch thick. 


3. Triple-ply is a new grade especially designed for cold storage, refrigerators, and other special 
work. It is about %-inch thick. 


4. Asbestos Quilt is the double-ply Quilt covered on both sides with Asbestos. The regular Quilt 
is very uninflammable, as fire will not spread through the eel-grass, but Asbestos Quilt adds to 
this and produces a fireproofing effect far superior to that of sheet asbestos because of the great 
heat insulating power of the Quilt. This prevents conduction of heat through to inflammable 
substances on the other side, and asbestos alone does not do this. It is the only sound deadener 
that is fireproof, and the only fireproofing that is an efficient deadener. 


5. Waterproof Quilt is the double-ply made with heavy waterproof paper. 


Shipment, Orders, etc. 
Quilt is shipped in rolls (pp. 1, 3), and each roll contains a continuous sheet eighty-four feet 
long and three feet wide, or two hundred and fifty square feet. Each roll contains tin caps for nailing. 
We always make prompt shipment and ship by the cheapest route unless otherwise instructed. 


Orders from parties with whom we have had no previous dealings must be accompanied by 


remittance or satisfactory references. 


Always specify the grade of Quilt desired.
